Li Jie was unwilling to toss again for a while, but the ball was soft and hard. Although he knew that there was something in the ball, he could only stare dryly, and there was nothing he could do.

"What kind of metal is this made of, this is too good!" Li Jie now wondered if it was a piece of metal, he had tried hammers, hacksaws, pliers and other tools, but the ball was not opened, but there was no trace left on the surface. He guessed that the ball must have been opened by a special method. In the case of violence, it may be possible to use an industrial drill or other chemical methods to destroy the ball.

"Forget it, it seems that it can't be opened now, so keep it first. Li Jie stared at the ball for a while, and finally had to give up. He put the ball in his bag and ignored it.

Although he was very curious about what was inside the ball, there was no way to open it, so he had to put it aside first.

Then he carefully took out the swollen pain powder he had obtained from Sun Ying's hand from the inventory. Because this thing looked quite dangerous, just in case, when he came back, he took advantage of Mu Qingqing's inattention and directly put it into the prop column.

The swelling powder looks like some tiny white powder, as if it is white wall ash, inconspicuous, and I don't know where Sun Ying got it.

He used insight on this thing again.

"Unknown chemical powder: can make people's skin swollen and painful, the recovery time depends on the individual's constitution, and the side effects are unknown. ”

The results of the Insight response were much the same as the last time he used them. This effect is completely in line with the basic idea of destroying first and then improving in hard qigong, and Li Jie guesses that this should be effective for hard qigong cultivation.

He carefully sat on the bed, sat cross-legged into the posture of hard qigong and luck, and then wiped a little on the palm of his hand, wanting to see if it had an effect on hard qigong cultivation.

Just smeared a little, with Li Jie's current hard qigong junior 43%, he couldn't resist, and the whole palm was swollen.

"It hurts! No wonder Liu Haoran screamed like something last time, it really hurts. ”

Originally, because of the proficiency of hard qigong, Li Jie only had to meditate for a period of time to enter a state of tranquility. But it is very difficult to calm down under the pain. But fortunately, the swelling and pain powder may really be due to Li Jie's physique, and the pain gradually decreased, and then Li Jie also successfully entered the state.

After entering the state, in the dark, he felt that his palms that had been painful were soaked in a hot spring, and a warmth surrounded those swollen places. Soon the pain subsided, but Li Jie was still in a deep state of calm. If someone can touch Li Jie's skin, they can feel that the temperature is very high, which has exceeded the normal human body temperature.

"Whew, it's so comfortable!" Soon, Li Jie slowly opened his eyes, and he felt that this cultivation was more successful than any previous one. He pinched the palm that had been smeared with swollen and painful powder, and found that it seemed to have increased a lot of toughness, and it seemed that the effect was not bad.

He opened the system and found that the hard qigong proficiency of 10,000 years of immobility was actually stained by 0.1%, although compared to using prestige to increase, this proficiency was not enough to plug the gap between his teeth, but this was also the skill proficiency that Li Jie improved with his own efforts.

But this swelling and pain powder is too little!

Li Jie estimated that he had to soak this small packet of swollen and painful powder in water to dissolve it, so that he could stool all over his body, and it really hurt to cultivate with this thing! It seems that he will work hard to gain reputation points in the future! and then exchange reputation points for huàn proficiency, which is much faster than his own cultivation.

Fortunately, Brother Hu, who also practiced hard qigong at the beginning, didn't hear Li Jie's thoughts, otherwise he would have been angry to death, you must know how much suffering he suffered when he practiced hard qigong at the beginning, and the rod hit his whole body, and he was scarred, which is not much more terrifying than using swollen and painful powder. If he knew that there was such a thing that could improve hard qigong, it wouldn't be crazy. No, it's all those who practice hard qigong to go crazy.

However, Li Jie didn't have such a consciousness, after using up all the swelling and pain powder, he saw that his proficiency no longer moved, so he had to wash and sleep. Through his efforts, the hard qigong proficiency eventually reached 43.5% at the elementary level

The next day, when he was leaving in the morning, he found that his sister Li Ying was mysteriously holding a bag containing a large number of paper cranes and didn't know what to do! I don't know what the hell my sister is doing?

Today, Li Jie is still trained in knowledge competitions. This time, Sun Bowen did not let the students do the questions, but conducted a unified analysis and guidance for the situation they did yesterday. And in the middle, there are many examples of math competition problems.

Li Jie has never participated in a knowledge competition, but after listening to Sun Bowen's guidance, he feels that he has gained a lot and has a clearer understanding of the knowledge competition. He believes that now as long as he is careful, it will not be a problem to get a perfect score.

Due to the short time, of course, Sun Bowen's explanation was very fast. Of course, the top students can keep up, but some students with insufficient strength are already a little confused.

When Sun Bowen saw the confused eyes of some students, he knew that the time of this training was too short, so he could only sigh helplessly. However, when he looked at Li Jie and the others who had good test scores yesterday, and saw these people listening to the lecture with great energy, he couldn't help but nod with satisfaction. These students are the key figures in this competition, and it depends on these students whether they can win the award.

"Okay, now that we've covered the basics of the competition, let's talk about our game and our opponents. Sun Bowen said to everyone when it was time for the final end of school.

"There are three rounds of this knowledge competition, the first round is a direct test for all participants, and only the top 100 are eligible to participate in the next competition. I don't need to say more, you also know that this is completely up to your own strength, enter the top 100, then enter the next round, otherwise you will be eliminated. The second round is teamwork, with each of the top 100 students divided into groups by school and competed as a team. If the team is eliminated, the whole team member will also be eliminated. In the end, only three teams remained, and then the final showdown began. But we just need to be in the top 10, and the top three are probably difficult for us to reach that height. ”

"Teacher Sun, if only one of us is in the top 100, what will we do?" asked a student curiously.

Even if only one person is in the top 100, it means that we are in Lincheng No. 3 Middle School. So you all have to work hard to get into the top 100, and the more people who make it into the top 100, the stronger the team in our school will be. Sun Bowen smiled: "Of course! If none of us make it to the top 100, then we can go home." I'm sure you don't want to see that!"

The students nodded, if that was really a shame, it was purely to make soy sauce.

"Let me tell you a little bit about our opponents. ”

"The first is Lincheng Shi Yàn Middle School, which is our old rival of Lincheng Middle School, and its strength level is about the same as our school. But your last one was lost at their hands. ”

"The catch is Xiyuan Middle School, which is a school that is stronger than us, so you must be careful when you meet you in the team competition. Sun Bowen instructed.
